Air Duct Cleaning in Houston, TX

Frequently Asked Questions

1. My Heights bungalow got central AC long after it was built — does that change how you clean the ducts?

   Yes, quite a bit. On 1910s-30s houses in the Heights and Montrose, the duct system was added decades after the house went up, so it's usually squeezed into a tight attic with a closet air handler and returns that are undersized for the house. That means less room to maneuver, more flex that sags between joists, and often a single central return doing all the work. We generally clean through the return and the registers rather than cutting large access panels where the trunk is hard to reach, and we'll tell you up front if a run is too crushed or disconnected to clean properly. In those cases cleaning it is the wrong fix.

2. We're near one of the bayous and have flooded before. Is there silt in our ducts?

   Often, yes. Water that reaches floor level gets into floor registers and low return boots, and when it recedes it leaves fine silt behind in the lowest sections of the system. It doesn't dry out and disappear. It sits in the boots and the bottom of the trunk and gets stirred up every time the blower runs. We check low boots and floor-level returns first on bayou-adjacent homes. If we find material that smells or shows signs of organic growth after a flood event, we'll say so plainly. Duct cleaning handles the debris, but soaked insulation or lined duct that held water usually needs replacement, not cleaning.

3. Why do my returns get filthy so fast here?

   Houston gives ducts more than their share. Homes near the I-10, 610 and 45 corridors pull in fine road and brake particulate, and that combines with the industrial haze that drifts from the Ship Channel side of town. On top of that, the live oak and pine canopy over most of the older neighborhoods drops pollen and organic debris for much of the year. All of it ends up at the return, which is why the filter and the return boot are usually the dirtiest parts of the system we see. Running the AC as long as Houston homes do means air is cycling through that return almost year-round.

4. What makes one Houston house cost more to clean than another?

   Mostly access and how many openings there are. A Loop-adjacent 1950s or 60s ranch with original sheet metal trunks and a reasonable attic is straightforward. A 1920s bungalow with a closet air handler, a cramped attic and ducts threaded through tight framing takes longer for the same number of registers. Two systems instead of one changes it. Under-slab supply runs, which still turn up in some of the older ranches, are a different job entirely, and we'll talk through whether cleaning them makes sense before anyone starts. Post-flood silt removal in low boots also adds time. We'd rather walk the house and count registers than guess over the phone.

5. Can you come out the same day, and how fast do you normally get here?

   Same-day happens, usually when something opens up in the part of town you're in. We route by area because crossing town during Houston traffic hours can cost more time than the job takes. Most people are scheduled within a few days. If you've just had water in the house or you're smelling something musty off the vents, say that when you call. We move those up because standing moisture in a duct doesn't get better with time. A standard clean on a single-system home is typically a morning or an afternoon, longer if the attic is tight or there's silt to pull out.
